Edwards Company, Inc., Syracuse, N. Y., a corporation or New York Application April 14,

Claims.

This invention relates to window constructions, particularly for vehicles, as buses, railway cars, etc., and has for its object a particularly simple and economical removable window guide con- 5 struction by which a removable window stop member is held in position by a bayonet-jointlikc connection and is applied first by a movement toward the fixed stop and then by a movement in a direction lengthwise of the fixed stop,

and is demounted by the reverse of these movements.

It further has for its object a sash guide unit which can be readily applied to the window opening or the post structure and which includes inner and outer members which form the sash guide, one of said members being mountable and demountable by successive movements in directions crosswise and lengthwise of the guide or sash to interlock the dernountable member with the other member.

It further has for its object. a sash guide in the form of a channel for receiving the sash, which channelincludes inner and outer members, one of which is stationary and the other removable,

these members having bottom flanges which fit edgewise, one within the other, and interlock with a bayonet-joint-like action or by movement of the removable member bodily toward the stationary member and then bodily lengthwise of the stationary member.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawing in which like characters designate corresponding parts in all the views.

Figure 1 is a fragmentary isometric view, partly in section, of a window construction embodying this invention.

Figure 2 is a fragmentary face view, partly broken away or in section, of the sash guide.

Figure 3 is a sectional view on line 33, Figure 2.

l designates the post structure of a window frame, which window frame is also termed with a sash guide designated generally 2.

3 designates the sash movable along the guide 2. In the illustrated embodiment of my invention, the guide 2 is in the form of a channel for receiving the margin of the frame member or stile 4 of the sash, the stile being of any suitable construction and having a weather stripping 5 which fits the channel.

The sash guide 2 comprises opposing members 1936, Serial No. 74,333

or sections 6 and l in the form of sheet metal strips angular in cross section and having side flanges which form the sides of the channel and bottom flanges. One of these members, as the member 5, is secured to the post structure or frame 5 and the other member I is removable, and the two members 6, l are provided with means which interlock with a bayonet-joint-like action or by successive angular movements of the removable member or strip 7 bodily to the other member or the sash in directions crosswise and lengthwise of the other member 6 of the sash guide. This interlocking means is provided on the bottom flanges of the members or strips 65, '5.

As here illustrated, one of the bottom flanges is formed with slots opening toward the edge of the other bottom flange and the latter is formed with hook-like projections for entering the slots and interlocking with shoulders projecting into the slots.

In the illustrated embodiment of my invention, the bottom flange of the fixed member or strip 6 is formed with slots 8 opening through its edge opposed to the edge of the bottom flange of the strip 7, which is co -planar with the bottom flange of the member 6, and the bottom flange of the strip 1 is provided with hook-like projections 9 for entering the slots edgewise. Also, the member 6 is provided with shoulders ill extending into the slots and with which the hook-like projections interlock. These shoulders Ill are here shown as struck from an additional or base strip 5 l underlying the bottom strips and secured, as by welding, at 83 to the bottom flange which is formed with the slots 8. This base flange extends the full width of the channel and the bottom flanges of the members 6, l together when assembled, extends the full width of the channel, with the bottom flange of the removable member or strip 1 overlapping the margin of the base strip l l The member 6 is secured to the post structure in any suitable manner, as by screws, extending through openings I l in its bottom flange and in the base strip l I. Also, the bottom flange of the stationary strip or member 6 is formed with slots l5 at intervals for receiving the bolt of a sash holder, not shown.

The strips or members 6, l are furnished with the sash equipment and applied by the body builder to the window opening. The stationary member 6 is first secured in the window opening in proper position. The sash is then placed in juxtaposition to the member 6 and then the removable member or strip 1 applied by a bodily movement, moving the hook-like parts 9 into the slots 8 and then by a bodily vertical movement hooking these hook-like projections behind the shoulders 10.

The demountable member or strip 1 is removed by the reverse of these movements.

What I claim is:

1. In a window construction, the combination of a window frame having a sash guide and a sash movable along the guide, the sash guide including opposing stop members forming a channel for receiving the sash, the members having angular portions extending crosswise of the bottom of the channel with the edges confronting each other, one of the stop members being removable, the angular bottom portion of one of the stop members being formed with slots in its edge opening toward the edge of the bottom portion of the other stop member and also with shoulders extending into the slots, and the bottom portion of the other stop member having hook-shaped parts for entering the slots and interlocking with the shoulders by successive movements of the removable stop member crosswise and lengthwise of the sash.

2. In a window construction, the combination of a window frame having a sash guide, and a sash movable along the guide, the guide including opposing members including flanges' extending crosswise of the edge of the sash, one of said members being removable and the flange of one of said members being formed with slots in its edge toward the flange of the other member and with shoulders extending into the slots and the flange of the other member being formed with hooks movable into the slots by bodily movement of the removable member flatwise toward the sash and into interlocking engagement with the shoulders by movement lengthwise of the sash.

3. A sash guide comprising opposing members, angular in cross section forming a channel for receiving the sash, said members having bottom flanges and one of said members being stationary and the other removable, the bottom flanges being co-planar and substantially complemental to each other, and one of the bottom flanges being formed with slots opening toward the edge of the bottom flange of the other member and the bottom flange of the other member being formed with hook-like projections for moving into the slots and interlocking therein by successive bodily movements in directions crosswise and lengthwise of said member, the member provided with the slots having shoulders extending into the slots with which the hook-like projections interlock.

4. In a window construction, the combination of a window frame having a sash guide and a sash movable in the guide, the guide including opposing sheet metal members, angular in cross section, and having opposing flanges forming the sides of a channel for receiving the sash and bottom flanges, one of said members being fixedand the other removable, the bottom flanges being coplanar with their edges confronting each other and the bottom flange of one of the members being formed with slots opening toward the edge of the bottom flange of the other member, and also having a strip on its inner side closing one side of each of said slots, the strip having shoulders extending into the slots, said strip extending substantially the full width of the channel, and the other member having its bottom flange lapping the adjacent margin of said strip and formed with hook-like projections for entering the slots and interlocking with the shoulders upon successive movements of the removable member crosswise and lengthwise of the sash.

5. In a window construction, the combination of a window frame formed with a sash guide, and a sash movable along the guide, the sash guide including opposing stop members forming a channel for receiving the sash, the members having angular flanges extending crosswise of the bottom of the channel and arranged in the same plane with their edges confronting each other, one of the stop members being removable, the angular flange of one of the stop members being formed with slots opening through its edge toward the edge of the bottom flange of the other stop member and also with shoulders extending into the slots, and the angular flange of the other stop being formed with projections for entering the slots and interlocking with the shoulders by successive movements of the removable stop members crosswise and lengthwise of the sash, said projection on the removable stop member lying in the common plane of the angular flanges of both stop members.
